Abstract

The present invention provides a computer system and a method for processing a debug message of a computer system. The method includes the following steps: performing, by a first timer, timing when a computer system starts up; determining whether a first-stage confirmation signal is received within a first specific time; stopping the first timer and enabling a second timer to perform timing if the first-stage confirmation signal is received; determining whether a second-stage confirmation signal is received within a second specific time; stopping the second timer if the second-stage confirmation signal is received; enabling an input pin of a general-purpose input/output (GPIO) device to be at a low level if the first-stage confirmation signal is not received within the first specific time or the second-stage confirmation signal is not received within the second specific time; and outputting a debug message based on the low level.

Dependent claims

A method for processing a debug message of a computer system, applicable to a computer system, wherein the computer system comprises a general-purpose input/output (GPIO) device, a firmware control device, a basic input/output system (BIOS), a first timer, and a second timer, and the method comprises the following steps:

enabling the first timer to perform timing when the computer system starts up;
determining, by using the firmware control device, whether a first-stage confirmation signal is received within a first specific time;
stopping, by using the firmware control device, the first timer and enabling the second timer to perform timing if the first-stage confirmation signal is received;
determining, by using the firmware control device, whether a second-stage confirmation signal is received within a second specific time;
stopping, by using the firmware control device, the second timer if the second-stage confirmation signal is received;
enabling an input pin of the GPIO device to be at a low level by using the firmware control device if the first-stage confirmation signal is not received within the first specific time or the second-stage confirmation signal is not received within the second specific time;
and
enabling the BIOS to output a debug message based on the low level.

a firmware control device, electrically connected to the output pin of the GPIO device;
a BIOS, electrically connected to the input pin of the GPIO device and configured to output a debug message;
a first timer, electrically connected to the firmware control device and configured to set a first specific time;
and
a second timer, electrically connected to the firmware control device and configured to set a second specific time, wherein when the computer system starts up, the first timer performs timing;
if the firmware control device detects that a first-stage confirmation signal is received within the first specific time, the first timer is stopped and the second timer performs timing;
if the firmware control device detects that the first timer reaches the first specific time, the input pin of the GPIO device is controlled to be at a low level;
if a second-stage confirmation signal is received within the second specific time, the firmware control device stops the second timer;
and if the firmware control device detects that the second timer reaches the second specific time, the input pin of the GPIO device is controlled to be at the low level, and the BIOS outputs the debug message in response to the input pin being at the low level.
